Centre Bearing on the 2018 Toyota Mark X: Purpose and Maintenance Tips

The 2018 Toyota Mark X, a popular mid-sized sedan in many markets, is known for its balanced performance and smooth ride quality. When it comes to drivetrain components like the centre bearing, it's important to understand whether this vehicle actually uses one and, if so, what role it plays in enhancing the car's functionality and what you should do to keep it in good shape.

Technically speaking, the 2018 Toyota Mark X is built on a rear-wheel drive platform with a relatively straightforward drivetrain layout. Unlike some longer or more complex drivetrains found in four-wheel drive or heavy utility vehicles, the Mark X's drivetrain does not incorporate a centre bearing. The reason is largely due to the design and length of the prop shaft system in this model.

Centre bearings are typically found in vehicles where the driveshaft is quite long, necessitating support to prevent excessive vibration, damage and wear. The Mark X has a single-piece prop shaft that is short enough to not require this additional support. Because the shaft is compact, it can rely on the transmission and differential mounts for support, avoiding the complexity and cost of adding a centre bearing. Simply put, the 2018 Toyota Mark X's design does not call for a centre bearing as part of its standard setup.

So, if someone is searching for a centre bearing for the 2018 Toyota Mark X, they are unlikely to find a genuine or OEM part because the vehicle does not utilise one. Instead, maintenance and potential parts replacement usually focus on the driveshaft itself, universal joints and associated mounts.

However, for vehicles that do incorporate a centre bearing, it's worth knowing why they are important and how you can keep them in good working order. Centre bearings serve as a crucial support for the driveshaft, especially when it is split into two or more sections. The bearing provides a pivot point and stabilisation, which helps reduce vibration and prevents the driveshaft from wobbling or suffering damage during rotation. This not only improves ride comfort but also extends the lifespan of the driveshaft and related components.

Centre bearings typically contain rubber isolators to absorb shock and dampen vibrations, alongside a metal housing and internal bearing that facilitate smooth rotation. Wear and tear can take a toll over time due to constant exposure to road conditions, dust, grime and heat. If the centre bearing starts to fail, drivers may notice symptoms like increased vibration while driving, knocking noises under acceleration or deceleration, and difficulty maintaining smooth driveline rotation.

For vehicles fitted with centre bearings, regular inspection during servicing is advisable. Mechanics will check the bearing's rubber isolation for cracks or degradation, listen for unusual noises and check for play in the bearing itself. Replacing a worn-out centre bearing early helps prevent further drivetrain damage and maintains vehicle comfort and safety.

Since the 2018 Toyota Mark X does not have a centre bearing, its maintenance routine skips this particular item. Instead, owners should focus on the health of the universal joints, transmission mounts and differential mounts as these parts compensate for the lack of a centre bearing by allowing some flexibility and support to the driveshaft. Like with centre bearings, any worn or damaged universal joints or mounts can lead to vibrations and noise, so they should be inspected regularly during services or if unusual symptoms are noticed.

In short, the 2018 Toyota Mark X offers a simpler drivetrain arrangement where a centre bearing is not used due to the short, single-piece prop shaft design. This reduces maintenance complexity and potential repair costs. Still, keeping an eye on driveshaft-related components ensures the vehicle runs smoothly and reliably for years to come.
